The main goal of aircraft modernization is the installation of the new Technology Refresh-3 component system. Kelly said most of the functions required for the upgraded F-35 depend on the capabilities of the Block 4 electronic warfare system.
During the upgrade, the entire configuration of the existing Technology Refresh-2 component system will be completely changed. Within the scope of the work, the system’s central processor, memory unit and avionics of the warplane are being developed. It is assumed that the updated components will provide 25 times more processing power for the new system compared to the old system.
In addition, as part of the modernization of the Block 4 electronic warfare system, the aircraft will be equipped with a new AN/APG-85 radar with an active phased antenna array. But the full list of changes remains a mystery.
